I have 6 of these, but can't use them since I changed my furnace. These have more decreased air flow than the standard ones, as they have a layer of active carbon for filtering odours. They are now hard to get, so if they are OK for your furnace, I'm happy to pass them on. They are all new in sealed packages.
